,Anrsxrn DEVICE;

Application filed November This im'ention'relates to anti-skid 'devices and .has for one ofiit's objects the production of' an inexpensive; device whichy may be easily installed upon the wheel of a motor car, and particularly t-hewheelof a Fordcar.

4Another.'object'is tllielproduction' of such a device in lwhichsever-al independent loops l of chain extend overft-he shoe, these loops beingV held upon the wheel by'devices from which the loops may readily disengage them.- selves when' partedby wear or other meansi These objects are .attained by themechanismI illustrafted'in the accompanying drawings. l ,Y j I For the purpose of illustrating the invenj tion, oneV preferredform. thereof is illustrat-v ed-in Vthe drawings, this form having been device embodying the principles of the presy ent invention.

Figure 2 represents a section on line 2,2 on Fig. 1, drawn to an enlarged scale, and

Figure 3 represents a section on line 3, 3 on Fig. 1, also drawn to an enlarged scale.

VSimilar characters indicate like parts throughout the several figures of the drawi-y ings.V

In the drawings 10 represents a hub of a 'wheel having radiating therefrom a plurality fof spokes 11 on the ends of which is mounted a felloe 12.A

On the felloe 12 is mounted a clincher rim 13 having a plurality of lugs 14 extending downwardly therefrom and contacting witl the front face of the felloe 12. f v

Through the felloe 12 and the lugs v14 extend bolts 15 having heads 16 on one end and nuts 17 on the opposite end.`

The rim 13 is adapted to hold upon the wheel the usual shoe 18.

Each bolt 15 not only extends through the felloe 12 and one of the lugs 14, but also extends through plates 19, one on the rear face of the felloe and one on the frontfacefthese plates being bent at 20 to bridge the lugs 14 while the rem-aining'portions `of each plate bear rigidly' against the'face of the felloe".v` In thev .bent portion 20 of the rear plate 19 is interposed a washer 21 ofthefsame thii'ckne'ssasi the lugs 14wso that the-"platesr19 s are interchangeable.

rFliese platesf19 are madein the Vform of segments of' a circ-le as indicated in Fig.v 1, andthe opposite 'endsthereofhave outwardly and downwardly extending ears 22 struck therefrom.

. The plates 1.9 have'also struck therefrom yielding tongues 23, the free ends of'whilch engage with the ears 22. 4 These ears 22 extendtlnough loops'y of chain. 24, each loop :being continuous andY` portions thereof passing over the shoe 18 in parallelism, as indicated in Fig. 1.

Each loop 24 is entirely independent of.` -the other loops forming the anti-skid device and in case a loopv becomes worn yto such an extent that it breaks, a few turns of the Wheel will cause Vthe lo'op'to becomevdis- 1 engaged from theears 22 .and `drop to 'the ground. This obviates the striking of wso chains against thev mud'guard ofthe car, v

which often occurs in anti-skid devices made of chains 4which are now in commonuse.

I When a loop becomes unserviceable it may be removed from the ears 22 and other loops placed in commission.

Should 'the tire becomepunctured so that i itis necessary to replace it, and it becomes necessary to remove the `rim 13, from the4 felloe 12, the'nuts 17 are unscrewed from the bolts 15 and the plates 19 are removed from *l the bolts and thrown over to 'the rear of the wheel to permit the rim 13 to be drawn olf the felloe while a newY shoeis being mounted thereon.

i When the new shoe is installed upon the.

rim, this rim may be again placed upon 'the felloe 12, the Vplates 19fbrought to the front of the wheel and inserted on the bolts 15 after which the nuts 17 are again screwed thereon retaining both the rim and the plates 19 in position.

Any movement of the plates 19 about the axis of the bolts 15 is preventedv owing to the upper portions of lthese plates 19 ,bearing against the projecting portions of the rim 13.

Should it be desired to use the car kwithout 'the anti-skid chains thereon, the various loops may, if desired, be removed from the ears 22, leaving the plates 19 yon the felloe. If it is desired, the plates may also be` removed, leaving the yWheelin its vnormal y condition.

This anti-skid device is particularly adapted Ford cars, but obviously it could be adapted for use on wheels of other cars. v

It makes a very simple means for preventing theslidding of cars which may be readily installed at a minimum cost, the plates 1.9.being struck from sheet spring metal, the ears and tongues being Vstruck up from the Vsame at a single operation by suitable ma- 4 Vvchi'nes.
